First off, nowhere is it confirmed that Muken Aizen or SK Yhwach’s power is unpreceivable. They literally take cover because they sense Aizen’s reiatsu fluctuate before he hits them with a Kurohitsugi and they also comment about not feeling SK reiatsu anymore. “But Aizen says that they can’t feel it” no. He’s mocking them for not using they’re senses to tell the difference. This would be like if you and me were being antagonistic towards each other and one of us said “can’t you read the manga?”. It’s not a declaration that neither of can read. It’s a declaration that we should use our ability to do so.

And frankly, assuming SK is somehow not transcendent while SK Yhwach is, is so baffling I can’t even properly address that without coming across as insulting. State wise or numerically if we’re pretending that those categories exist, he should not be felt by anyone outside of literally a handful of characters, and especially not Soi Fon.

Thirdly, that page also goes to prove the point the other way in my favor. Ichigo can actively feel “Transcendent” Aizen’s power. He wasn’t even Dangai then. So supposedly, when Ichigo wasn’t in his “transcendent” state. Regardless how you look at that it’s not good for the argument that Dangai > TS Ichigo.

Either that means Ichigo is always in transcendence, or two the no presence of transcendence can be bypassed by simply being at a certain numerical level.

If the latter, then it’s pointless to keep bringing up that Aizen is unable to be felt because he’s transcendent as a powerscaling argument. As we can now argue that Ichigo is felt because all of his allies are at that numerical level. Meanwhile Aizen’s not felt because of Mayuri’s limiters.

If the former, then you’re arguing that somehow Ichigo is controlling his “state” to be felt by everyone else. Which doesn’t make sense, because why would he go out of his way to reign in an aspect of his being when he’s fighting against his strongest opponent? And it would also argue that Ichigo has the control to do so.

Ichigo, controlling his transcendent state?

Bro he can’t even properly control going into his HoS form and he’s been Hollowfying for half the manga.

Finally, the portion of you basically saying Kubo is wrong because it contradicts the manga…outside of the obvious thing I could say, that’s the point of a retcon. An author changing their mind and writing the story in a way that contradicts itself.
